CULTIVATOR.

SPECIFICATION forming part of LettersPatent- No. 752,852, dated February 23, 19Q4.

Application iiled August '7, 1903.

To all wiz/0m it may concern.'`

Be it known that I, JOHN NAGEL, acitizen of the United States, residing `at, Springfield,- in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Oultivators, of which the following is a specification.

`My invention relates to improvements in cultivators, more particularly adapted to twohorse cultivators having two independent series of shovels.

The improvement consists in the constructions shown and described hereinafter, whereby I have a machine easily adjustable for varying conditions of use and adapted to give the best results on account of the adjustable features contained therein. The adjustable features are in the seat of the driver, such that the adjustment can be made for an operator heavy or light in weight.

Another feature is in the adjustment of the shovels to different positions and the automatic adjustment of the carrying-Wheels therewit Another feature is the adjustment of the height of the seat for the operator and in the peculiar arrangement of the parts.

In the accompanying drawings, Figure 1 is a plan view of my machine. Fig. 2 is a side elevation. Fig. 3 is a detail view of the adjusting device for the shovels connected with the hand-operated lever. Fig. 4L is a detail view of the connections with the foot-lever. Fig. 5 is detail View of the adjusting devices for the seat. Fig. 6 is a detail view of adjusting devices for the carrying-wheels. Fig. 7 is a detail of the connecting devices between the frame of the machine and the shovel.

Like parts are represented by similar letters of reference in the several views. y

A and B indicate theframe of the machine, to which the tongue of the machine is connected.

C C represent the carrying-wheels, which are supported by the frame of the machine in the manner hereinafter explained.

Tothe frame of the machine there is attached by a clip a( a downwardly-projecting U-shaped piece a2. (Best shown in Fig. 7.) This piece is pivotally supported withinthe Serial No.`168,685. (No model.)

clip a', which is fastened to the frame by nuts. There is journaled loosely upon the said piece a2 a sleeve as, formed of twoparts bolted together, which is integrally formed with a bracket a4. This sleeve has oblong openings formed therein, (marked m5,) Fig. 7, and within these openings there fits a connecting-bolt a, which is fastened to the U-shaped piece a2 at the point a7.- The purpose is to adjust for the width of cultivators.

The bracket a4c is formed with openings as, and within this bracket is adapted to be connected the drag-bar of the shovels,it being understood that there is one of these supporting-brackets on each 4`side of the frame, as shown in the drawings. This drag-bar is indicated by a, Fig. 2, and is formed at its head with a bracket-shaped piece am, which fits over the piece als and is pivotally connected to said piece by bolts au. I have shown in this manner a connection for the drag-bar of the shovels or drags such that there is some vertical movement of the drag-bars due to the oblong shape of openings a5 and also some lateral movement of same through pivot-bolts all, as well as `permitting a sliding adjustment of the sleeve a3 for variation in cultivators.

The U-shaped piece a2 is formed integrally with a downwardly-projecting plate w12, formed with openings am, and within one of these openings there is adapted to be fitted a rod` a, which is curved at its end, as shown in Figs. 2 and 7. The other openings are for the swingletrees of the machine. a extends toward the rear of the machine, and the rear end of same fits within a loop@15 on a iatbar a, Fig. 2, which is connected to the frame of the machine.

There is a U-shaped piece a2 for each series of shovels, andin the machine shown here I have illustrated the usual `construction employing twonseries of shovels. Each U-shaped piece is formedin the same manner and the con nections with each are the same as those just explained. The bar am is at its rear end, Figs.

\ 1 and 6, connected to a sleeve (marked b) by a clip. There is a bar and a sleeve for each carrying-wheel. yThis sleeve is supported by a plate b' and is journaled loosely on a shaft if `Theshaft b2 is curved at its downward This rod IDO end and is formed with a spindle 53, which constitutes the axle of the driving wheel. The plate 5 rests upon the top side of the spindle, and there is formed within the lower part of the sleeve 5 a ball-race 51, and Vballs 55 are adapted to t within said ball-race to form a ball-bearing between the plate 5 and the sleeve. There is a similar connection between the sleeve and shaft at the top. The upper end of the shaft 52 is formed with a square projecting piece 58, and on this piece is tted one end of the frame for the carrying-wheels, (marked 57, Fig. l.) There is an oblong opening formed in the end of the framev 57, and the shaft is pivoted within the opening to said frame.

On each side of the machine-frame there isy supported a lever-arm 58 at the front end of which there is formed a plate 58 with a series of openings 51, Fig. 3. A pin 511 projects upwardly from the carrying-wheel frame 57, and this pin is adapted to fit within the openings 51, so that when the arm 58 is raised the adjustment can be made from one opening to another. The lever-arm 58 is pivoted at 512 to a bar 518, shaped as a double crank, so that the front end of the lever-arm 58 can be raised by depressing the rear end of same. The rear end of said lever-arm is connected with a lever 511, which is adapted to be depressed by the operator seated on the seat of the machine. A spring 515 normally holds the rear end of said lever-arm 58 in its extreme upper position, and thereby holds the front end of same in engagement with the pin 511,' but when the lever 511 is depressed the rear end of said lever-arm will also be depressed against the tension of the spring 515 and thev front end of the lever-arm be raised so that lateral adjustment of said arm can be made. Whenever said arm is moved laterally, the pivotal connection 512 is such that the bar 518 is rotated thereby, and the lower end 581 of said arm is moved laterally for the purpose hereinafter explained. The lower end of the rod or shaft 518 ts within an opening formed by the bracket 515, which is part of the drag-bar for the shovels. Consequently whenever the lower end 581 of the bar 513 is moved laterally theshovels will be moved a corresponding distance. At the same time the carrying-wheel will also be moved simultaneously by reason of the connection between the frame 57 and the axle of the wheel.

As shown in Fig. 1, I have two series of shovels and a corresponding lever-arm 511, with its connecting parts, for each series, so that the operator by operating both levers simultaneously willeiect a quick and accurate adjustment of the parts for cultivating. I have also shown a connection with said shovelframe 57, so that the operator can adjust same by moving the foot.

In Fig. 4 I have shown a lever 518, which is fulcrumed on a support 517, which projects from the frame-piece 518, which is supported by the frame B. At the upper end of this lever 51 there is a pivotal connection with -a crank-arm 518. The lower end of said lever 51G is formed of alshape for easy manipulation by the foot; The crank-arm 51g is pivoted on top of the side pieces of the frame B, the tonguepiece tting Within a mortise formed in the frame-piece 518. The clip shown in Fig. 4 binds the tongue to the frame-piece and also forms the pivot for the crank-arm 518. The crank-arm at one end is pivotally connected with the upper end of the lever 518. At the other end the crank-arm 518 is pivotally connected with the shovel-frame 57. Consequently whenever the foot of the operator causes the lower end of the lever 518 to move inwardly or outwardly the crank-arm 518 is correspondingly moved, which causes a lateral movement of the frame 57. By this construction the operator may by depressing the rear end of the arm 511 raise the front end of the lever-arm 58 and adjust the lever-arm so that with the foot he may operate the lever 511, and thereby cause a greater or less lateral adjustment of the series of shovels, depending on the opening within which is fitted the pin 511. The bar a1 is formed at the front end with a series of openings, so that when it is desirable to change the position of the axis of the carrying-wheels the operator can loosen the nut 581 and move the bar a1 forwardly or rearwardly. When this is done, the lower end o1' the sleeve 5 is moved out of vertical line. The upper end of the sleeve is formed with a projecting piece 588, having a convex face formed thereon (marked 583) which permits an adjustment of the upper end of the sleeve by reason of the convex face 523 being formed so as to slide over the face of the bar. The sleeves and projecting pieces constitute a supplemental frame for the carrying-wheels. When adjustment is to be made, the bar C418 is moved forwardly or backwardly,which throws rear end of sleeve 5 backward, which throws the fulcrum point for the machineframe rearwardly and changes the balance to provide for change in weight of operator. In this manner the sleeve and shaft are adjusted and same are held in the adjusted position by tightening the bolt 5X. The opening through the piece 528 is oval shaped, and the surface against which the head of the bolt abuts is curved, Fig. 6, so as to make a secure adjustment. The seat c for the operator is supported by a brace c. (Shown in Fig. 5.) This brace has a series of openings at its upper end, and the front end of the seat-bar 08 is connected with a stepped piece c3, which engages with the Jframe-piece 518. By releasing the bolt c1 the seat-bar o8 and the seat c can be lowered or raised, and the stepped piece c3 can then be adjusted to engage with its notch the frame-bar 518, so as to lholdl the seat-bar securely in its adjusted position. (See Fig. 5.)

The sleeve a8 can be moved laterally on the U-shaped piece a8 and when adjusted to proper IOO IIO

position the connecting-bolt a can be adjusted to engage one of the openings a5, so as to hold the sleeve in its adjusted position.

The series of shovels are connected by a chain d witha lever UZ, which is used in connection with the segment d2, so that the shovels can be raised or lowered and heldin their adjusted position. In order to avoid interference between the lever and chain, I have shown the lever of a bracket shape, Fig. 2, which insures easy and quick adjustment of the shovels.

In operation it will be understood that the driver seated upon the seat o can quickly shift the drags or shovels for preventing the plowing up of hills of corn. For instance, 4if there are hills of corn out of line which the machine would otherwise plow up the operator can by depressing the lever b1* immediately disconnect the shovel-frame from the carrying-wheel frames and by a lateral movement of the lever b can throw the shovels to the right or to the left, so as to prevent any injury to the hills of corn. If, however, the operator desires to change the direction of the entire machine, he lifts the lever Z214 in its raised position, so that when he throws the lever Z214 to the right or left he moves the carrying-wheels simultaneously with the shovels and in this manner changes the direction of the wheels.

Having thus described my' invention, I claim- 1. In a cultivator, the combination of the carrying-wheels, the carrying-wheel frame, shovels, and a shovel-frame pivotally connected to said carrying-wheel frame, a lever normally holding the carrying-wheel frame and shovel-frame connected, and means connected with said lever for causing the two frames to move in unison whenever said lever is moved laterally, but adapted to permit said lever to move vertically and thereby disconnect the two frames, for the purpose specified.

2. In a cultivator, the combination of the carrying-wheels, the carrying-wheel frame, shovels, and a shovel-frame pivotally connected to said carrying-wheel frame, a lever normally holding said frames connected and adapted to cause same to move in unison whenever said lever is moved laterally, separable connecting devices between said lever and said carrying-wheel frame, .and means for disengaging said lever from said separable connections by the vertical movement of said lever while holding connected said lever and the shovel-frame, for the purpose specied.

3. In a cultivator, the combination of the carrying wheels and the carrying wheel frame, a series of shovels and shovel-frames pivotally connected to said carrying-wheel frame, a series of levers normally connected to said carrying-wheel frame and the shovelframe and adapted to be moved laterally, means for moving all said frames by the lateral movement of any one of the levers, and means operated by the vertical movement of said lever for disconnecting any one of said shovel-frames from the carrying-wheel frame, for the purpose of operating any one of said shovel-frames independent of the carryingwheel frame.

4. In a cultivator, the combination of a carrying-wheel frame, a shovel-frame, a lever pivotally connected to said shovel-frame and adapted when operated laterally to throw said shovel-frame to the right or left, an arm on said lever separably connected to the carryingwheel frame at one end thereof, and means connected with said lever for operating simultaneously the shovel-frame but adapted to cause the disconnection of said frames whenever said lever is moved vertically and carryingwheel frame, for the purpose specified.

5. In acultivator, amachine-rame, a carrying-wheel frame, a rod extending from the front of the machine-frame to the supplemental carrying-wheel frame and connected therewith, a sleeve journaled loosely on said carrying-wheel frame, a convex face formed on its upper end, and means for changing the relative position of said convex face and the machine-frame, for the purpose specified.

6. In a cultivator, the combination of a machine-frame, a carrying-wheel frame, and a supplemental frame for said wheel-frame, a rod extending from the front of the machineframe to the lower end of the supplemental carrying-wheel frame, a convex face formed on the supplemental frame and engaging the machine-frame, and means for adjusting the position of said convex face in its relation to the machine-frame, for the purpose speciiied.

In testimony whereof I have hereunto set my hand this 28th day of July, A. D. 1903.
